#include <CGAL/Classification/Feature/Echo_scatter.h>

Inherits from

CGAL::Classification::Feature_base.

Definition

Feature based on echo scatter.

The number of returns (echo number) is a useful information provided by most LIDAR sensors. It can help to identify trees.

Its default name is "echo_scatter".

Template Parameters
GeomTraitsmodel of CGAL Kernel.
PointRangemodel of ConstRange. Its iterator type is RandomAccessIterator and its value type is the key type of PointMap.
PointMapmodel of ReadablePropertyMap whose key type is the value type of the iterator of PointRange and value type is GeomTraits::Point_3.
EchoMapmodel of ReadablePropertyMap whose key type is the value type of the iterator of PointRange and value type is std::size_t.
